I'm trying to avoid the scroll bar appearance on an UIComponent. Is there any way to obtain the computed width/height that my container component should have to have all children visible? I don't want to compute it myself. I would like to know if there is any variable computed by the component when it decides if it should draw the scroll bar or not.
View 0 RepliesI have a VBox inside a Canvas. The 'red bars' are custom components based on 'Canvas'. All red bars are of equal height. I have 20 red bars inside the VBox. The scrollbars visible in the screenshot are the Canvas's scrollbars. The scrollbars of the VBox are disabled using verticalScrollPolicy = off.
Without scrolling, only 16 red bars (and a part of the 17th bar) are visible. However, when I scroll down the Canvas I expect to see the remaining red bars - but the bars that are not visible when the application starts don't get 'drawn'. What am I doing wrong? I want the user to be able to see the 17th - 20th bars when the Canvas is scrolled down.
My question is: Set parentSprite.visible = false will make all children in parentSprite all invisible, right? And is there any way to just make parentSprite itself invisible without effecting it's children?

I'm currently working on a custom component which extends Canvas (let's call it SuperCanvas) ; it's basically a container that let you zoom & pan its contents. It would be too long to explain why, but I can't use scrollRect, so I was forced to declare a Canvas object (called innerCanvas)... inside my SuperCanvas (I know, not very nice =/) I would like to know if there's a proper way to "redirect" the creation of my component's children in this canvas.

I have a little trouble in managing the children my container. The fact is that it has a lot of children and their y coordinates are very random.
Is there anyway i can order them by y coordinates that the lower will be in the front and the higher with be in the back?
is it something that that I can do with 2 "for"?
This may well just be because it can't be done but here goes.Does anyone know of a way that I can make a MoviecClip "visible=false" whilst stopping just one of its children's, children's, children...etc from also going invisible.I am aware that it can be done by setting them all individually but this will take a lot of code (and I like tidy code...and I'm lazy), and I am reluctant to use a loop as it will interrupt the animation that is going on at the time.
View 2 RepliesThe issue I'm having is that I have a main "wrapper" 100x100 (but it could be any size) - it's just there to hold and display whatever content, swf, gif, etc we may want to throw into it. As long as the loaded content doesn't have 3D animation like rotationY going on, it displays fine. But when it does, the 3D "anchor" properties (like projectionCenter) of the loaded swf inherit those of the main timeline (i.e. 100x100 (main) vs 728x90 (loaded)). If I change the dimension of the main "wrapper" in Flash IDE to match what's coming in - the 3D behaves fine, but I won't know what the dimensions of the content will be until it comes, so I need a way (if there is one) to dynamically alter the main "wrapper" or root display object through AS. Stuff like "this.width = loader.width" or "stage.width = loader.width" or "root.width = loader.width" etc doesn't work. Flex has the hBox and vBox
View 1 RepliesWell I'm starting to really enjoy AS3, my next question then is this: In AS2 I'd often remove all movieclips with something like this:
PHP Code:
for(var i: String in container) {
container[i].removeMovieClip();
}
Is there something similar in AS3 that I can do without resorting to maintaining an array of references to each child of my container?

I have a simple swf in an invisible <div>; when user mouseover's the <div> becomes visible.The swf has a ExternalInterface.addCallback( "..." , ... ) to create connection to js that needs to be called at load, such that by the time user mouseovers the flash-js connection is working.PROBLEM: on windows safari the flash does not go through its loading sequence until the user finally mouseovers
View 1 RepliesI am having trouble determining where to add my removeChild() statement to clear multiple movieClips from a container mc. I know I need to determine if the container movieclip contains anything. I don't know how or what I should put and where to put it. If I can determine if my container mc has movies in it, I am assuming I can just declare it again (i.e
PHP Code:
panel= new MovieClip();
)to clear it. Am I correct?

I'm using as container for my LinkButtons. I would like to know
1) How can I remove the space between the items in my Tile container.
2) How can I set dynamic width for my items (at the moment they all have the same width regardless the width of the included component)
3) How can I avoid to display scrollbars if the items are not included in the container
If I have a container, and I set clipContent to true, how do I get the total height of the children inside it? Is there a method for doing this without itinerating through every child and summing the heights?
View 1 RepliesAt one point in my script I'd like to check a MC for the number of children and limit this number to 3. For that I use this script:
Code:
if (container.numChildren > 3){
for (i = container.numChildren; i > 3; i--){
container.removeChild(container.getChildAt(i-1));
popError('Horizontal nur 3 Elemente!');
}
}
This somehow works fine if there are 4 or 5 children in the MovieClip, but as soon as there are 6 or more, it throws an Argument Error #2025 and does not remove anything. BTW it does not make difference if I use container.removeChildAt(i-1);
i'm getting the #1010 error... code below:
Code:
var curProject:int = 0;
var curExample:int = 0;
var container:MovieClip = new MovieClip();
im.addChild(container);

View 4 RepliesI'm using an accordion container that has it's creation policy set to auto. One of the accordion's children is a spark border container that has a data grid within it. Currently, I'm using the data grid's creationComplete property to call a function; similarly, I'm using the dragComplete property to call another function.
How can I add listeners for events (creationComplete & dragComplete) via actionscript? The obvious problem is that the accordion does not create all its children on creation (nor do I want it to), so I can't simply use something like: datagrid.addEventListener(...)
is it possible to retrieve all children of a certain type from a parent in actionscript 3? i only see getChildAt,getChildByName, is there a getchild of a certain type like get all childs of object type:Food?

View 4 RepliesI've got the following situation, where I have an outer Vbox that is set at a fixed width, and then inside it there is a header made from an HBox and a content area (Canvas) that is much wider than the enclosing VBox (and therefore requires scrollbars on the outer VBox to see it all).
I would like to set the width of the header to fill the entire width of the outer container, but only the visible part, and to remain fixed so that when I scroll to view the content, the header doesn't move.

I have a tree with a dataprovider which takes the following form:
<details name="Cars">
<contact_person>aaaa</contact_person>
<list>
[Code].....
That is I want to hide the contact_person and list nodes.Deleting the nodes from the dataprovider cannot be done.So what i did was to create a custom tree data descriptor by extending DefaultDataDescriptor.Then override the getChildren method and applied a filterfunction to the collection returned by super.getChildren.The problem is when i hide the 'list' node I cannot have the child nodes to show up.So is there any way I can hide 'list' but show the children of 'node'?
Is there an easy way to make a parent container (eg Group) resize when it's children resize?
Below is a little example app. When I put the 200x200 'food' in the 'stomach' the stomach & it's containing 100x100 'body' should resize to contain the food.

If I've got a Container with a child component that is off either the top or the left hand side:
Is there any way to get scroll bars to show up? ie, so I can scroll up and get the button back in view, the same way I could if the button was off the bottom right side?
I have code like the following:
<s:VGroup gap="10" id="group" height="100%">
<s:Label text="This is page 2" />
<s:Button content="Resize Canvas" click="resize(event);"/>
<mx:Canvas id="photoCanvas" color="#567898" backgroundColor="#125567">
</mx:Canvas>
</s:VGroup>
I don't understand why the following does not work:
Pushing the Button resizes the photoCanvas's height (gets taller or smaller). Since the photoCanvas control is a child element of the VGroup shouldn't the container update itself to the new height? The Vgroup has ALWAYS the same height, no matter what the (total) height of the children is! I would like the VGroup to adjust itself and get a height value equal to the sum of its children heights. Is this not possible??
Flex's new States re-parents visual items that are marked with includeIn/excludeFrom. If I have a Group (MainGroup) with 5 children/elements that are state controlled, is there still a way to get a reference to MainGroup's children? mainGroup.numChildren and mainGroup.numElements don't work since the children are re-parented. At best, they show 1.

<s:State name="view1State" />
<s:State name="view2State" />

I'm having sizing issues with a TabNavigator. The direct children of the TabNavigator are Canvases, and within these I am adding Images. I'm trying to resize the images to fit within the Canvas without scrollbars. The Canvas height is set to 100% of the parent, which is the TabNav. Then I'm setting the image.height = parent.height *.9. The result is that Flex is generating scrollbars because the images are too high. It appears that the root cause is that the height property of the TabNavigator is the height of the entire component, including the height of the tabs. I'm assuming therefore it also contains that little strip of space between the tabs and the children of the TabNavigator. This makes sense, but is there a property that returns only the height of the children? I'm aware of the scrollbar policy properties and I've experimented with those. I know I can also try a different multiplier for the image size to get it to fit. It just seems like there should be a property to get the size of the space for the children.
